[APM] MIPS: Convert to use shared APM emulation.

Also convert to use generic kernel/power/Kconfig to make the use of the
shared APM emulation possible.

-	  APM is a BIOS specification for saving power using several different
-	  techniques. This is mostly useful for battery powered systems with
-	  APM compliant BIOSes. If you say Y here, the system time will be
-	  reset after a RESUME operation, the /proc/apm device will provide
-	  battery status information, and user-space programs will receive
-	  notification of APM "events" (e.g. battery status change).
-
-	  In order to use APM, you will need supporting software. For location
-	  and more information, read <file:Documentation/pm.txt> and the
-	  Battery Powered Linux mini-HOWTO, available from
-	  <http://www.tldp.org/docs.html#howto>.
-
-	  This driver does not spin down disk drives (see the hdparm(8)
-	  manpage ("man 8 hdparm") for that), and it doesn't turn off
-	  VESA-compliant "green" monitors.
-
-	  Generally, if you don't have a battery in your machine, there isn't
-	  much point in using this driver and you should say N. If you get
-	  random kernel OOPSes or reboots that don't seem to be related to
-	  anything, try disabling/enabling this option (or disabling/enabling
-	  APM in your BIOS).
